Dive Response

Billy orders a plant for his garden. When it was delivered, the roots and the plant stem were not growing straight out of the clay pot. Instead, the direction of their growth was in a 'sideways' direction. The diagram shows the direction the plant was growing when it was received by Billy. Why is the most likely reason for the direction of the plant growth?

• The plant lost turgor pressure and changed it's growth direction.

• The plant was laid on it's side inside the package and geotropism caused the plant to change it's growth direction.

• The plant found light through the sealed package and phototropism caused the plant to change it's direction of growth.

• Plants normally grow in strange patterns until they reach a certain age.
